Yes, it is true the above pic is the real size of the projector, things are changing.
The unit is able to display images and video at a resolution of up to 640 x 480 pixels.
Nonetheless, a VGA connector allows users to plug the MPro 110 into a laptop. It’s also compatible with connections from a range of portable devices, including digital cameras and the iPhone.In a dark room, it could project a big enough image to be the ultimate cheap-o home theater. The projector will sell for a mere $359. It doesn’t have a speaker, so you’ll have to get that separately. But really, how good could a microscopic speaker jammed into this thing sound, anyway?
The standalone projector goes on sale September 30. In a year or so, 3M hopes to squeeze it into cellphones.
